My computer stops working whenever I connect anything to the usb.

Your treadmill may not be turning on due to a broken or a failed power supply or a broken power cord or a tripped circuit breaker switch a failed circuit breaker switch a bad power switch or wiring failure or a bad motor control board or failed console display screen can stop the treadmill from turning on. If the outlet is not working try to reset the house circuit breaker which is located inside of the fuse box to restore power to the outlet.

It is fused through the house circuit breaker.

Hi, Are you getting a "USB device not recognized" error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!

However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!

So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn't work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn't work!

I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!

You may also see in Device Manager that the device shows up as an "Unknown Device".

So how did I finally fix the problem? Well, apparently it's a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.

Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that's it! Note that this does not mean just turning off your computer because modern computers don't really turn off when you press the power button as the motherboard still gets power.

First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be "rebooted" also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!

So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.

Hope this helps someone fix that pesky "USB device not recognized" Windows error!


Have a nice day...

Here is a solution I posted today for a similar issue. Might fix your problem.

Did you notice if there was anything else not working in the house? If so, most likely a breaker tripped. If it did, then there is a problem with the circuit. Unplug everything on this circuit and try resetting the breaker. If it still has problems, call in a licensed electrician to troubleshoot the problem.
Did anyone work on anything prior to this event? May be a loose connection. turn off ALL the power in the electrical panel before you work on the fan because you have no idea which breaker (or fuse) operates this unit. Check all the connections in the fan. If the connections are good then we need to stop here because more details would be needed.

Well, it’s a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.

P.S. if it is a laptop, power up the laptop with just the batteries, not plugged in to fix this issue.

Give this a try and come back to tell us if it worked or not.

try using a different usb port. might be the pc just can't detect your cam.

i'm not sure if this will work but try reseting it by pushing ON/OFF, Record and hold at the same time. if that doesn't work you can see if you can take the battery out.
